OPERATION
This is the safety alert symbol used for the OPERATING
INSTRUCTIONS section of this manual to alert you to
potential personal injury hazards. Obey all instructions to
avoid possible injury or death. IMPORTANT: Before
attempting to raise any vehicle, check vehicle service
manual for recommended lifting surfaces.
OPERATION:
To raise load: Turn the handle in a clockwise direction until tight.
1.
Position the jack under the load. Proceed to pump the handle in
order to raise the lift arm to the load. As the saddle at the end of
the lift arm gets closer to the load, reposition the jack so the saddle
will contact the load firmly and the load is centered on the saddle.
Make sure the saddle is correctly positioned. Raise the load to the
desired work height. Place jack stands of appropriate capacity at
the vehicle manufacturers's recommended support areas that
provide stable support for the raised vehicle. DO NOT CRAWL
UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING OR
REMOVING THE JACK STANDS! Once jack stands are positioned,
turn the handle VERY SLOWLY in a counterclockwise direction
Lower the load to rest on the jack stands. Inspect the relationship
between the jack stands and load to make sure the setup is stable
and safe. If the setup is not stable or safe, follow the preceding
steps until corrected.
2.
To lower load: Follow the procedures mentioned in "To raise load"
section of the OPERATING INSTRUCTIONS in order to raise the
load off the jack stands. Once the load has cleared the jack stands,
remove the stands from under the load and away from the work
area. Turn handle very slowly in a counterclockwise direction until
the load is completely lowered to the ground. Once the jack's
lifting saddle has cleared the load, remove the jack from under the
load.
CAUTION: Keep hands and feet away from the hinge mechanism of
the jack.
3.
Air may become trapped in the hydraulic system during shipping
and handling. Trapped air will affect the pumping performance of
the jack. If this occurs, follow the air purging procedure below:
a) Remove the four screws that secure the cover plate (A) to
the jack frame (B) so the oil filler screw (#21) can be
removed from the hydraulic power unit reservoir tube (#38).
b) With the lift arm (C) in its down position, look inside the oil fill
screw hole. You should be able to see the top of the power
unit's cylinder (#29). The hydraulic fluid level should be no
higher than the top of the cylinder. Correct the fluid level if it
is not at the proper height.
c) Pump the jack against a load that is at least 500 lbs. (225
Kgs). After the load is raised, slightly turn the pump handle in
a counter clockwise rotation so the load is very slowly
lowered. While the lift arm is lowering, quickly pump the
MFJ354P
MFJ354P 3-1/2 Ton Service Jack
If the pumping condition has improved, repeat steps "a" through "d"
until all of the air has been purged from the system.
OWNER/USER RESPONSIBILITY
The owner and/or user must have an understanding of the
manufacturer's operating instructions and warnings before using this
jack. Personnel involved in the use and operation of equipment shall
be careful, competent, trained, and qualified in the safe operation of
the equipment and its proper use when servicing motor vehicles and
their components. Warning information should be emphasized and
understood. If the operator is not fluent in English, the manufacturer's
instructions and warning shall be read to and discussed with the
operator in the operator's native language by the purchaser/owner,
making sure that the operator comprehends its contents. Owner
and/or user must study and maintain for future reference the
manufacturers' instructions. Owner and/or user is responsible for
keeping all warning labels and instruction manuals legible and intact.
Replacement labels and literature are available from the manufacturer.
INSPECTION
Visual inspection should be made before each use of the jack, checking
for leaking hydraulic fluid and damaged, loose or missing parts. Each
jack must be inspected by a manufacturer's repair facility immediately
if subjected to an abnormal load or shock. Any jack which appears to be
damaged in any way, is found to be badly worn, or operates abnormally
MUST BE REMOVED FROM SERVICE until necessary repairs are made
by a manufacturer's authorized repair facility. It is recommended that an
annual inspection of the jack be made by a manufacturer's authorized
repair facility and that any defective parts, decals or warning labels be
replaced with manufacturer's specified parts. A list of authorized repair
facilities is available from the manufacturer.
PROPER STORAgE
It is recommended that the jack be stored in a dry location with all
wheels touching the ground on a relatively level surface.

handle 5 or 6 full incremental pump strokes. After pumping,
lower the lift arm to its full rest position.
d) Install the oil fill screw (#21). Rotate the handle in a clockwise
rotation until tight and pump the lift arm to maximum height.
e) Install the cover plate (A) with the four screws.
